Stress. Life’s trauma, physical or non-physical, can cause a flight-or-fight, or a freeze, stress response. Most experience it. Some are crippled by it. So how can stress, the body’s responses to what life throws at us, be assessed? Researchers think they have found a new approach. It lies in going back to the source of the body’s stress responses, with evaluation of brainwave asymmetry between the left and right sides of the brain’s temporal lobe.
